Problem: The PS/2
®
Port mouse or the PS/2 pointing device does not work.
Solution: Make sure that the TrackPoint and the touch pad are set to
Automatic in the ThinkPad Configuration Program. Then detach the PS/2
®
Port mouse or the PS/2
®
pointing device, and try using the TrackPoint and
the touch pad. If the TrackPoint and the touch pad work, the error might be
due to the PS/2
®
Port mouse or the PS/2
®
pointing device.
Make sure that the cable for the PS/2
®
Port mouse or the PS/2
®
pointing
device is securely connected to ThinkPad Port Replicator, Port Replicator II or
MiniDock.
Note: For more information, see the manual supplied with the mouse.
Problem: The mouse buttons do not work.
Solution: If your ThinkPad computer has the TrackPoint only, this problem
may occur.
Change the mouse driver to Standard PS/2
®
Port Mouse, and then reinstall

directory on your hard disk drive. If your hard disk drive does not contain

open Access IBM by pressing the Access IBM button.
Standby or hibernation problems
Problem: The computer enters standby mode unexpectedly.
Solution: If the processor reaches a temperature that is too high, the computer
automatically enters standby mode to allow the computer to cool and to
protect the processor and other internal components. Also, check the settings
for standby mode, using Battery MaxiMiser.
Problem: The computer enters standby mode immediately after Power-on
self-test (POST) (the standby indicator light turns on).
Solution: Make sure that:
v The battery is charged.
v The operating temperature is within the acceptable range. Refer to
“Specifications” on page 5.
If these items are correct, have the computer serviced.
Problem: The critical low-battery error message is displayed, and the
